The Marlborough Public Library will host local writer Marty Foley and coauthor Tom Farmer for a talk on their book, “A Murder in Wellesley: The Inside Story of an Ivy-League Doctor’s Double Life, His Slain Wife, and the Trial That Gripped the Nation,” from 6 to 8:30 p.m. Tuesday. The book, published in October, tells the story of the 1999 murder of Mabel Greineder. Foley, a State Police detective at the time, led the investigation into her death.
